When a Word 2010 DOCX file, that contains inking annotations, is uploaded to a document library the ink is then no longer visible in the document, and it is unable to be edited and saved back to the library.
This issue DID NOT exist previous to the DEC 2012 Cumulative Update Version 14.0.6131.5003.
If the Parser is disabled using ParserEnabled = $false, then the issue disappears.
It is obviously a bug relating to the Document Promotion/Demotion feature of SharePoint, and I believe it was introduced in the 14.0.6131.5003 version of the Office Document Parser (offparser.dll).
It does not seem to be a widely reported issue, but it is easy to replicate. On a vanilla install of SharePoint Server in a test environment, the CU produces the same issue.
I would appreciate any assistance by the Microsoft engineering team on this issue.
Other Information:
Version: SharePoint Server Standard 2010 SP1 with KB2596955 (DEC CU) applied.
Server: Windows Server 2008 R2 SP1
Hardware: Virtual Hyper-V Environment
Office 2010 Professional Plus SP1
P.S. I have also managed to test the BETA of Service Pack 2 for both the Office Applications and SharePoint Server and the problem is still present in SP2.
